This news makes me think about a HOward Stern interview that he did with Ron Howard... Ron Howard was shockingly open, and Stern of course diverted the conversation to sex at a point and asked about a rumor he'd heard about Don Knotts being quite the skin hound...

Ron Howard acknowledged it, and that Knotts had different women often, but that he wasn't ever exposed to what went on though now he's sure it was going on quite often. He said Andy would personally take him off the set when things were "getting rowdy" and they'd go hang out and tour other studios and stuff.

He was, I guess, quite cautious with Ron Howard's growing up in the spotlight, and wanted to make sure he had as normal a childhood as he could, and that he was taken care of and not exposed to too much.
